  • Textile Printing The Past and The Present

  • What is Textile Printing?

    Textile printing is the name given to certain processes which are used to produce single or multi-coloured patterns on fabrics.

    Textile printing is normally carried out at the fabric stage and sometimes at the garment stage

  • How Fabrics are Printed ?

    Fabric preparation

    Design artworks

    colour separation

    exposure

    Printing paste

    Printing

    Fixation

    Washing-off

  • Traditional Screen Printing

  • Printing Paste

    Highly concentrated dye solution

    Thickened to prevent excessive stike-through and bleeding

    Fixation chemicals added

    Dyestuff must be chosen for the fiber type.

  • Recipe

    Dyestuff

    Solvent

    Thickener

    Fixation chemical

  • Example: Cotton

    Reactive dye (Procion H)

    urea

    water

    sodium alginate thickening

    Resit Salt L

    sodium bicarbonate

    print>dry>steam>soaping

  • Example: silk

    Basic dye

    Glydote BN

    acetic acid

    water

    tartaric acid

    thickener

    Print>dry>steam>rinse

  • Example: polyester

    Disperse dye

    sodium alginate thickener

    emulsion thickener

    Perminal KB (fiber swelling agent)

    print>dry>steam>soaping

  • In traditional textile printing the build-up of dyes has

    to be considered and is influenced by the following

    factors:

    substrate

    pretreatment of material

    print paste composition

    amount of paste applied

    fixation

    etc.

  • The Latest Digital Textile Printing Technology

  • Orders for designs decrease

    Shift to higher value

    Shorter fashion cycle

    Shorter lead time

    Price pressure increasing

    Growing costs for sampling and small orders

    Environmental pressures continually magnify

    Worldwide Textile Printing Market : Market Trend

  • flexibility in production

    Traditional printing can be efficient if you need to produce 20000 mts. of one design,

    but what if you need 1000 mts. of 10 designs?

    Why DTP?

    GREENTechnology

    Dramatically reduced waste of dyes & chemicals:

    Few g/sqm consumption with low unfixed dye amount to be removed

    No need for color kitchen process color concept

    Less energy/water needed for processing:

    Size of machinery adequate to digital

    Safetyand comfort in printing environment

  • Color Reproduction

  • Digital is a way to overcome the limitations of traditional printing

    No limitation in numbers of colors

    Excellent Shade gradations & 3D effects & length of rapport

    Low cost sampling, screen print sampling unstainable, low hit rates

    No color kitchen, no screens, colors mixed on fabric

    No minimum orders

    Sustainable technology

    Low amount of unfixed dyes, less water

    and energy for washing, less color in effluent

    Just in Time Printing

    Minimal time between sample approval and production

    Fast response to ever changing design collections

    Lower stocks for whole supply chain

    Main Advantages of Digital Printing

  • IS THIS THE END FOR THE FLAT SCREEN PRINTER?!

    No one amoung the manufacturers will invest money to develop new improvements on the conventional

    machines.

    SUSTAINABILITY

    low energy consumption (electricity, water)

    low enviromental impact

    easy washing off

    friendly chemistry

    LESS INVESTMENTS

    small working area

    machiness prices

    less consumption

    MORE PROFIT

    sampling cost is like producing cost

    sampling offer dramatically increases

    BIG SAVINGS

    no engraving

    no stock of screens/cylinders

    no colour kitchen

    DTP means

    The New Scenario

  • Comparison process Traditional vs Digital

    Traditional Digital

    Number of ColourLimited to the number of Cylinder & Screen ( 8/15 ) Unlimited

    Max Dimension of

    the design

    Repeat 640 mm most common

    Repeat 1180 very rare

    Unlimited

    Type of the design

    and shades

    Limited to the type of mesh ( Cost )

    Of the cylinder

    Very detailed with linear shades due to the perfect

    gray scale

    Defects and

    selvedge banding

    Sometimes difficult to avoid or eliminate Not existing

    Ecology impact Very High due to the waste for washing

    cylinder & engraving and printing paste

    Near to Zero

    Minimum quantities &

    order quantities & orderVery high cost per meter influenced by

    cost of the cylinder

    Practically Zero

    Dead Time setting for

    changing design

    Very high depending on no. of cylinder & washing Zero

    Personel Involved 2 man for Machine plus 1 for Colour Kitchen plus 1

    for service

    1 person for an industrial mach.

    Time for Sampling

    design

    Depending on engraving but in general 3/4 weeks Real time

    Cost of collection

    and sampling

    Very high due to the people involved

    engraving time

    Very low

    Performance of the

    Machine

    Up to 50 m / min up to 75 m/min

  • Fastest growing application sector in textile coloration

    Technology has replaced automatic flat-bed screen printing in terms of cost and efficiency

    EU traditional screen printers started conversion to digital 10 years ago leading the way

    Technology has enabled textile printing to remain and thrive in EU

    Apparel printing on CEL,Silk & PES coupled with intricate digital design fueling the growth.

    Home textiles, outdoor articles, flags, soft signage, automotive, sportswear, T-Shirts all existing and developing sectors

    Conversion from Screen Printing to digital is Conversion from Screen Printing to digital is

    taking place in all Markets
